WALES Six Nations squad members Robin McBryde, Dwayne Peel and Barry Davies will be thrust into action by injury-ravaged Llanelli Scarlets tonight.

Gareth Jenkins throws the three of them into the frame against the Celtic Warriors with an incredible 30 of his 40-strong Scarlets squad nursing injuries.

Catalyst Scott Quinnell has been ordered to rest for a month by a top London specialist as he attempts to overcome a groin injury in time to face Biarritz in the quarter-finals of the Heineken Cup in April.

Wales winger Mark Jones and club captain Leigh Davies are among their other big-name casualties.

Jones has also targeted the European showpiece after being ruled out of the Six Nations because of knee surgery, while centre Davies is recovering from a hamstring injury after previously being out with knee and ankle problems.

Others on the sidelines include hard-working flanker Ian Boobyer, who is recovering from a broken arm, and Canada prop Jon Thiel, who has a knee problem.

"It is good that some of our Welsh players have been released," said Scarlets assistant coach Nigel Davies.

"Wales coach Steve Hansen specifically asked if we can play Dwayne and Robin, we are happy to oblige.

"Each of them will start the game. Dwayne has not had much game time recently and Robin needs to get match fit after a back injury.

"We are delighted to have them back because we have been struggling to put a team on the field recently.

"Medically, we have been told Scott needs complete rest.

"By his own admission, he plays his best when he gets a run of games but, gradually, his injury became more chronic.

"Scott is a huge influence on the team but, having said that, when he is unavailable, the team is able to adapt to other tactics."

The Scarlets are second in the Celtic League, two points behind leaders Ulster, and would go top if they win at the Brewery Field tonight and the Irish province lose at Newport in tomorrow's clash with the Dragons.

"It has been a matter of fine-tuning our preparation for Friday night.

"It is based on the opposition and what they are likely to do and developing our own robust patterns of play," said former Wales centre Davies.

"It is going to be a massive game. It is a top end of the table clash for us for the third week running.

"The Warriors have got a certain amount of momentum. They had a fantastic victory over in Leinster last week and they are going to be very difficult to play on their own patch."
